%0 Journal Article %T Gravitational excitons from extra dimensions %A U. Guenther %A A. Zhuk %J Physics %D 1997 %I arXiv %R 10.1103/PhysRevD.56.6391 %X Inhomogeneous multidimensional cosmological models with a higher dimensional space-time manifold are investigated under dimensional reduction. In the Einstein conformal frame, small excitations of the scale factors of the internal spaces near minima of an effective potential have a form of massive scalar fields in the external space-time. Parameters of models which ensure minima of the effective potentials are obtained for particular cases and masses of gravitational excitons are estimated. %U http://arxiv.org/abs/gr-qc/9706050v2
